Communication and Perception

Apis mellifera communication is based on chemical signals, and most of their communication and perception behaviors are centered around scent and taste. The members of the hive colony are bound chemically to each other. Each hive has a unique chemical signature that hivemates use to recognize each other and detect bees from other colonies.

Within the hive, bees are in constant chemical communication with each other. Workers feed and groom each other, as well as larvae, drones, and the queen. In the process they pass on pheromones, chemical signals that indicate information about the health of the queen and the state of the colony.

Chemicals not only help with detecting the right signature of hives but also with foraging. Honeybees use scent to locate flowers from a distance. When a successful forager returns to the hive, it passes the scent of the flowers to its nest mates, to help them find the same patch of flowers.

Bees also use chemicals to signal outside the hive. When a worker stings something, her stinger releases an alarm pheromone that causes other bees to become agitated, and helps them locate the enemy.

Thought it's always dark in the hive, vision is important to honeybees outside. They can see other animals, and recognize flowers. The eyes of Apis species can detect ultraviolet light wavelengths that are beyond the visible spectrum. This allows them to locate the sun on cloudy days, and see markings on flowers that are only visible in ultraviolet light. One portion of honeybee's eyes is sensitive to polarized light, and they use this to navigate.

Workers and queens can hear vibrations. New queens call to each other and workers when they first emerge. Workers hear the vibrations of the waggle dances made by returning foragers.
